SKATES PATENT UFFICE ALBERT BUJE'WSKI, OF ST. LOUIS, MISSOURI.

\VEATHER-STRIP.

To all 107mm it may can earn:

Be it known that I, r'irLnnn'r BUJnwsKr, a citizen of the United States, residing at St. Louis, in the county of St. Louis (-ity and State of Missouri, have invented a new and useful rfeather-Strip, of which the following is a specification.

i 'his invention relates to weather strips, and is an improvement on Patent No. 872,649 granted to me on December 3, 1907.

'ihe object of the present invention is to provide .means for mar-:ing a close joint between a door sill and a door when the latter is closed, whether the coacting surfaces be true and in exact parallel relation or not.

A further object of the invention has reference to means for increasing and decreasing the movement of the pressure bar to adapt the device for use on doors with more or less lateral space between the bottom rail of the door and the door sill.

TTith these and other objects in view the invention consists of the construction, combination and arrangement of parts herein after described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a side view partly broken away of a portion of a door and its frame with the invention applied; Fig. 2 is a horizontal section on the line 22 of Fig. 1 Fig. 3 is a cross section of Fig. 1 on the line Fig. 4 is a view of the rear edge of the door at the bottom; and Fig. is a perspective view of the lower end of one of the movable members. Fig. 6 is a view showing in perspective a modified form of the device. Fig. 7 is a view of this modification in cross section. Fig. 8 is a detail view showing the arrangement of the spring for moving one of the bars of the device.

Similar reference numerals are used for the same parts in all the figures.

The numeral 1 indicates a door frame of which 2 is the sill. Hinged in the door frame in the usual manner is a door 3 having a groove in its bottom edge 4 to receive the casing containing the operative members of the weather strip 6, said members and the casing extending from the hinge edge to the loci; edge of the door.

The operating members of the weather strip comprise a longitudinally novable bar 7 slotted at various points in its length to receive anti-friction rollers S. The bar 7 is re tained in place by a separating strip 9 fixed by pins or otherwise to the casing Next Specification of Letters Patent.

1908. Serial No. 425,248.

the separating strip is a laterally movable pressure bar 10 between which and the separating strip are connecting springs 11 which prevent longitudinal movement of the pressure bar 10 but yield freely in a lateral direc tion. Fixed to the inner or rear face of the pressure bar 10 are a plurality of cam blocks 12 which extend through slots in the separating strip and lie with their cam surfaces in contact with the anti-friction rollers 8. From the above it will be noted that when the longitudinally movable bar 7 is operated, the anti-friction rollers 8 bearing on the cam blocks 12 will cause the pressure bar 10 to move dowmvardly and press on the door sill 2 and when the longitudinally movable bar 7 is relieved, the pressure bar will be returned to place by the springs 11, and, through the cam blocks and rollers, the bar 7 will be returned to normal position.

The outer or bottom side of the pressure bar 10 is preferably of a concave shape to re ceive a soft resilient packing strip, such for instance as a rubber tube 13, fastened therein in any suitable manner.

Thus far the weather strip is substantially the same as that described in the patent heretofore cited to which reference may be had for a more detailed description.

hen the door is opened the longitudinal bar 7 is forced toward the hinge edge by a spring 14 and the springs 11 which latter also draw the pressure bar 10 upwardly and away from the door sill 2 so that the door may be swung on its hinges with ease, but as soon as the door is closed and latched, the bar 7 is moved longitudinally and forces the pressure l, ar 11) against the door sill 2, producing thereby a tight joint. The packing 13 being quite resilient any irregularities on the sur face of the door sill, or any departure from exact parallelism of said sill and the bottom of the door, or the parts of the weather strip attached thereto, will be overcome by causing the pressure bar to move a greater or less distance, the soft packing, yielding under the pressure of the packing bar, produces an aosolutely tight joint.

The means for causing the pressure rod to move laterally a greater or lesser distance will now be described. Mortised into the door frame 1 in line with the longitudinally movable rod 7 is a narrow metal case 19 rectangular in form and open on two of its edges as shown in Fig. 2. \Vithin the case 19 is a gear wheel 20 mounted in a rocking frame 21 pivoted near the bottom of the casing on a pin 21 fastened on one side of the case 19. The opposite end of the rocking frame is movable, and connected to a member of an L-shaped lever 22 the other member 16 of which extends through a slot 23 in the side of the door frame and is provided with a thumb nut 25 by means of which the rocking frame and the gear wheel 20 may be moved to any required position and held there by tightening the thumb nut.

Projecting from the rear end of the rod 7 are two spaced lugs 26, between which is journaled a small gear wheel 27 that extends beyond the plane of the rear edge of the hinge stile when the door is open and enters an opening in the door frame 2 in juxtaposi tion to the large gear wheel 20 when the door is fully closed. Now, by adjusting the gear Wheel 20 so that the Sll'iitllfll' gear wheel 27 engages with it when the door is more or less closed, the longitudinal movement of the bar 7 will be greater or less accordingly, and the lateral movement of the pressure bar will vary therewith. It will thus be seen that the extent of lateral movement imparted to the pressure bar can be adjusted with great exactness.

From an inspection of Fig. 2 of the drawings, it will be understood that as the door is swung from open to closed position, the gear 27 will engage with the gear 20 and both gears will rotate toward each other to a slight degree, probably the extent of two or three teeth. This rotation of the gears obviates sticking of the end of the bar 7 which would likely occur if the end of the bar engaged with a fixed stop.

In a modified form shown in Figs. 6 and 7 the device is intended. to be used solely as a weather strip and in this connection comprises a central core 28 preferably rectangular in form. On this core is slid a tube of rubber or the like material indicated at Surrounding the core on three sides is then formed a metallic casing 30 preferably concentric with the core 28 and so arranged as to I closely embrace the tubing 29 and hold the same and the core firmly in position while permitting the tubing to project on the third side as indicated by the dotted lines in Fig. 7. At each end of the casing is provided suitable fastening means as indicated at 31 whereby the same may be secured to the window frame. In this form of the device it is seen that there is providerjl a simple and cconomical form of weather strip.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

r l l 1 l l tudina 1. A weather strip comprising a casing seated in the bottom edge of a door, a longitudinally movable bar, a laterally movable pressure bar operated in one direction by said longitudinally movable bar, and springs between said bars for moving the pressure bar in the opposite direction, a soft resilient sacking fastened to the outer surface of said pressure bar and adapted to bear on the door sill, an adjustable bearing surface seated within the door frame against which said longitudinally movable bar strikes when the door is closed, and an adjusting lever connected to said bearing surface and extending on thr ugh said frame to permit the adjustment of said surface when the door is closed.

2. A weather strip comprisin a casing seated in the bottom edge of a door, a longitudinally movable bar, a laterally movable pressure bar operated in one direction by said longitudinally movable bar, and springs between said bars for moving the pressure bar in an opposite direction, a soft resilient packing fastened to the outer surface of said pressure bar and adapted to bear on the door sill, automatic means for moving saidv longitudinally movable bar in the opposite direction when the door is opened, an adjustable bearing surface seated within the door frame against which said longitudinally movable pressure bar strikes when the door is closed and a lever connected to said adjustable bearing surface and extending outwardly through the casing to adjust said surface when the door is closed.

3. A weather strip comprising a casing seated in the bottom edge of a door, longily movable bar, a laterally movable pressure bar operated in one direction by said longitudinally movable bar, and springs between said bars for moving the pressure bar in tne opposite direction, a soft resilient packing fastened to the outer surface of said pressure bar and adapted to bear on the door sill, an adjustably inclined stop within the door frame, a lever connected to said adjustable stop extending outward through the casing and arranged to move said step while the door is closed, an d a wheel or roller on said longitudinally movable bar adapted to contact with said stop and move said pressure bar.

In testimony that I claim the foregoing as iy own, I have hereto affixed my signature in the presence of two witnesses.
